To all whom #may concern."

. Be it known that l, limoni B. SMITH,`a

citizen of the United States, and aresident-of Worcester, in the count fof Worcester and State of Massachusetts, have invented a new andusefullmprovement in I tacles, ol which the following is aspecification', this being a division ci my application,

4My invention-relates to tanks or receptacles which are constructed ofconcreteor other molded material, and has special rei-einu ence toinclosing casings for Huid-insulated electric apparatus. The object ofmy invention is to provide an inclosing casing or tank, of an improvedand 'economical construction tbatsliall be ada t-V ed to contain aninsulatingl fluid, such as oil.` According to prior practice,- bolleriron or steel inclosing tanks .bave usually been ero-A ployed to containrelatively higli-voltage,. transformers, and

oil-immersed electrical these tanks were sometimes disposed in cellsconstructed of brick or pense of. a construction siderable and the tankconstruction closing tank or casing itself is constructed 'of concreteor a similar substance Which .may be the application of .a suitableluideresistinglcoating or by employing a sheet instal lining, vmayadvantageously be i ein loyed in lieu tliereot'.

Referring to the drat' ings,- tlietank l comet) prises Walls 2 oi material thickness Wln'oliareconsiu'uctedbi concrete or similar molded material and a sheet metal@lining 3. The side Walls of the ,tank 'are reierably reinforced bymetal rods 4 Wliic are placed in position in a Well known .manner whenthe Walls are in process or" construction.

'lt may be found desirable to coat tbe interior of the tanl with-varnish'or otner snitable materialwliicli Wi prevent the il orother'luid contained in the tank from escapin through thepores ci thestructure.
